CONCRETE RAILWAY-TIE.

Specification of Letters Patent. Patented July 12, 1921;

Application.filed` October 30, 1920.V Serial No. 420,605.

lle it known that wal/Vianini J. LANK- rono and lVALrnn H. CHAPPELL, citizens of the United States, residing at Chanute, in the county of Neosho and State oflansas, have invented a new and Improved Concrete Railway-Tie, of which the following is a specification.

This invention has reference to improvements in railway ties, particularly concrete ties and primarily our said invention has for Vits purpose to provide an improved construction of railway tie of the general character stated composed of a plurality of sections in endwise alinement and adapted for being readily connected or assembled to the operative condition and for cooperative connection withmeansfor readily attaching the parts and for disconnecting them in such manner whereby removal and renewal of the said parts may be expeditiously and conveniently accomplished.

Another and essential feature of our invention is to provide a concrete railway tie of a practical and relatively economical construction, in which the rail clamping and bracing elements are combined and connected for holding the rails down under the desired rigidity against spreading, and in such manner that lateral strains on the rail, particularly on curves, are so taken care of that danger of the rails creeping sidewise along the tie surface is reduced to the minimum, the several parts that constitute our improved construction of cement tie being also so designed whereby the end to end sections of the tie body are so Ijoined thata suflicient flexibility or an elastic yielding of the parts is provided for so that when relieved of the cars weight, the said parts will relax to admit of the normal contraction and expansion of the 'rails and keep them from creeping orsliding on the tie and the strain and wear on the said tie materially overcome.

lVith other objects in view that will be hereinafter generally referred to, our invention embodies certain features of construction and novel arrangement of parts, all of which will be fully explained in the following detailed description, specifically pointed out in the appended claims and illustrated in the accompanying drawing, in which:

Figure lis a top plan view of our concrete tie and illustrates a preferred construction thereof.

Figs. l() and 11 are respectively a plan view and an edge View of the tie plate.

F l2 is an elevation view of the hook or connecting device for joining the adjacent ends of the `longitudinal connecting or rail clamping rods.

Fig. 13 is a diagrammatic side elevation of a further modification of our invention hereinafter specifically explained.

In the drawings in which like numerals designate like parts in all 0f the figures and referring more particularly to Figs. l and 2, the body portion of the'tie consists of two like half sections 1 1, which sections are disposed end to end and in longitudinal alinement and, in the practical development of our concrete tie, the outer end of each section has a clover leaf or three lobe shape, as shown in Fig. l, the opposite sides and the end faces being vertical. and formed with panels or recesses 2 2, the latter providing for a tight embedding of the tie in the ground, when'placed in position for use and for convenient handling' of the body sections 1 1. when placing the same in operative po-` sition or removing them, when necessary.

Each of the tie sections l .has a countersunk recess 3 at the inner end and the said recesses7 when the tiesections are adj acently positioned,v form a spaceinto which is received a cushioning block il, the purpose of which is to take up and intercept vibrations of the tie body, such formation of the adacent ends of the tie sections also avoiding the effect of rigidity of the tie.

The rails 10--l0, in my construction of concrete rail tie, do not rest directly on the 7 tie top but engage metal plates 5 that are hereinafter termed tie plates, the application of which vand .the ,means for holding them secure upon the top of the tie sections 1 and the clamping devices that coperate therewith and the rails being best shown in Fig. 3.

By referring now to the aforesaid Fig. 3 and Figs. 10 and 8, itV will be noticed lt-hat the plate 5, at its outer edge, has a central recess 50 and, .at the opposite edge, it has a centrally disposed aperture 51, the purpose of which will presently appear, it also having apertures A46--6 at the opposite ends in each of which is received a combined clasp and 4bolt 7, .the latter serving as spikes for clasping over the adjacent rail flange of the rails.

The bolts 7 have angled portions 70 at the lower end for coengaging with reinforcement plates 8 that extend .across and under the' main or draw bars `9 Whoseouter ends terminate in upward and backward turned hooks 90 for Afit-'ting over the outer rail lian e and for opposing the bolts 7, las is cleary shown in the drawings.

Cushion members in the nature of elongated plates 11 seat under the tie plates 5 and their inner oppositepedges are secured by the clasp or hook 7.

The outer edges of :the plates' 11 are notched and stradyd'le the hook ends of the draw bars 9.

12--12 designate keepers 'that are embedded in the cement sections 1 and each of the said keepers has an inturned hook 12a that ts overL the outer edges ,of the tie plates 5 at each side of the opposite ends of the draw -bars 9 ,and in `addition to holding down thetie plates the ysaid keepers avoidV spelling of the concrete at the outer edges .of the said tie plates.

The body sections 1-1 each have a channel lor groove that extends lengthwise thereof from near the outer ends-to and th-rough the inner end and at the said inner end, the grooves iti-16 terminate in depressions or enlargements that forni a sufficient space or Vseat for receiving and for the free 'adjustment of a turn buck-le 17 (or other like coupling device) that joins the inner adjacent threaded ends `of the draw bars 9-9 Whose outer hook-shaped ends engage the outer ,fianges of t-he rail, it being understood that, by proper adjustment of the turn buckle 17, theV bars 9 may be drawn together or relaXed for holding the'opposite rails, for the proper `setting thereof.

To further hold the rails against spreading or outwardly creeping, brace members 19 are provided and they are held in engagement With the outer face Aof the rail Webs, Vthe innermost'end of the said brace contacting the under side o f the head or tread portion of the rail and -for effecting a strong and durable connection for the brace, Whereby to adapt it for taking up the lateral outward stress on the rail, ,the said braces include base portions 19a that seat in the outer- .mostpend Aof the longitudinal channels or grooves 16 and abut the outermost edges of the hookends'of the draw rodsl 949, as best shown inVA Fig 3, by reference to which it Will be observed each brace portion 19a includes an outwardly extended clutch member 19", Vwhich members are .apertured for Areadily fitting. over the projected threaded ends of the bolts 2O embedded in theV concrete bod-y and which receive clamp nuts 21 that secure the brace ends' 19a down onto the tie body.

29,-22 designate ordinary headed bar members and they are embeddedin the tie body, when pouring the cement into the desired -t-ie vbody andthe said bar members have their ends projected laterally at the opposite sides Vof the meeting ends the body sections 11-1 and V,2B-23 denote hook mem- 'bers that extend across the gap between the ends of the body sections 1-1 and hook over Y the heads of the members-or bars as is clearly show-n in Figs. 1 and 2.

Instead of shaping the ends ,of the con-V necting devices 233-23 as shown in Figs. 1 Y

and 2, the said devices may be formed as shown in Fig. 12, by lreference to which it will be noticed the angled ends of the connecting bar have bayonet slots 23a for slipping over the heads of :the bars 22 andinter-lockably sliding along the Shanks of the said angled ends. j

Referring nonT more particularly to Figs. 3, 41, Vand 6 of the draw-ings, it will be noticed that the spike or clasp bolts 7 are rotati-vely mounted with respect to the rail base so that they may be readily turned to 4one side in a plane parallel with and outside of the said rail base, as is clearly indicated in the detail view, Fig. 5, it being understood that, when the members 7 are posi ioned as in Fig. 5, the rail may be readily lifted out of the operative position 4,aiong the tie, it being also apparent that when the mem-bers 7-7'are turned at" right angles to the rail base and extended over the said base, by `tifglitening upV the draw bars Cl- 9, a rigid connection for holding the rail upon the tie is provided for.

To secure the clasps or belts 7-7 in their clamping position, key plates 24 are provided that are held downV 'between the adjacent sides of a pair of spikes or bolts by key bolts 25 that pass down through theV key pla-tes 24 and Vwhich are -held bet-Ween the adjacent pairs nof spikes cr clamp members 7 7, when the latter are projected over the Y through elongatedslots 95 in the draw bar members 9 and also through cushion plates that engage the under side oli' the draw'bar 9 and" with which the angled portions on thelower end of the bolts or clasps 7 engage, when such bolts are adjusted to the rail base clamping position, as is clearly indicated in Figs. l, 2,3*and ln Fig. 7 is shown the means for clamp ing the rail onto the tie and, in this form ol my invention, the same general arrangement of parts appears as in Figs. l, 2 and 3, the dili'erentiating feature being that in addition to the draw bar hoolr'connections for the outer base flange ot the rail, a pair oit' rotatable spikes or clamp members 27 2? are provided, whose lower ends pass through cushion plates 28, which extend diagonally under the rail Vand have their inner ends apertured `for passing the lower ends of the inner bolts or clasps 7m?, as indicated in dotted lines in the said' Fig. 7.

rinotherl modication ot our concrete tie construetionis indicated in TEig. 18. ln this form, the spikes that clasp the inner base flange of the rail are shown as embedded in the tie body and the outer flange oi' the rail held down' clamp plates 35, and nuts 3b which engage the upper threaded end 8T ol' tired rods embedded in the cement body and wiose upper threaded ends are so disposed with relerence tothe rail base i'lange that the plates o5 and the nuts 36 may be conveniently applied.

In the several forms ofour concrete tic structure hereinbefore described and illus tratedlin the drawings, the outer ends of the body sections of the tie have projected headed studs 60 that are provided for engaging with slotted ways 6l in vertical adjustable wings or shields 62 that are provided to prevent wastage of the filling while tamping at the ends ol' the tie, particularly when the tie ends are concaved on their un der side as indicated by dotted line on Fig.

ln the practical assemblage oi' the parts that constitute our improved construction oi concrete tie, the rail rece ving ends are reinforced by longitudinallyY extended meta-l bars or plates and like transversely placed bars or plates T6 shaped shown in dotted lines of Figs. 3 and 7 and which extend down into the tie body where they pass under the part of the tie where the rail crosses as indicated in Fig. 7, such placing ot' the reinforcing members T5 causing the weight that comes onto the tie to tend to draw endwise on the reinforcement.

While the speciic arrangement ot' the parts shown and described illustrate one practical presentation ot our invention we do not limit ourselves to such specific details ot construction since in the practical development ol our improved concrete tie the special arrangement of parts may be modilied or varied as conditions of ourapplication of our`improved tie may make necessary, without departing from our invention as comes within the scope of theappended claims.
